Kinetic study of NaBH4 hydrolysis over carbon-supported ruthenium

The effects of temperature and the concentrations of NaBH4, NaBO2 and NaOH on the rate of NaBH4 hydrolysis over carbon-supported ruthenium catalyst were investigated using isothermal rate data extracted from non-isothermal reactions. It was shown that the hydrolysis was a zero-order reaction with respect to the concentration of NaBH4 and the reaction rate decreased with the increase in OH− concentration. A rate expression was then derived to correlate the hydrolysis rate with the temperature and NaOH concentration.
